EV 10 and Exchange 2010

    Enterprise Vault Partitions that belong to Vault Stores will be assigned per EV Server So you would have something like VaultStore1 (on EVServer1) Partition1 -> E:\Partition1 Partition2 -> F:\Partition2 VaultStore2 (on EVServer2) Partition1 -> E:\Partition1 Partition2 -> F:\Partition2 Let's say you have Exchange1's Archiving Task on EVServer1 and Exchange2's Archiving Task on EVServer2 You enable Archiving for a user on Exchange1, EV then creates an archive on VaultStore1 You enable Archiving for a user on Exchange2, EV then creates an archive on VaultStore2 If a user gets moved from Exchange1 to Exchange2, although the users Task that archives the users mailbox is on EVServer2 , the users archive still belongs to VaultStore1 When an item gets archived in the users mailbox, it gets passed from EVserver2 to EVserver1 to store the item in the archive

Oh sorry, didn't see saying Copies. then yeah only Active Databases will be archived, not the copies etc
But anyho, based on that guide, if a DAG failover occurs and the users mailbox is now being archived by a task on another server, the following applies (which i mentioned originally)

"Yes, it is possible that performance would be affected. For example if you have a scenario where you have a 1:1 relationship of 1 Enterprise Vault server per Exchange Mailbox Server and with a DAG configuration similar to that of the customer scenario in this document, if MailboxDatabase1 fails over to MailboxServer2, once the provisioning task has run, the mailboxes in MailboxServer2 will now be processed by the second EV server as that is the server that hosts the archiving task for MailboxServer2. In addition to already archiving mailboxes in MailboxDatabase3 and MailboxDatabase4, the second EV server now has to process mailboxes in MailboxDatabase1 and MailboxDatabase2. In that event the Enterprise Vault server will have more mailboxes to process, and because the storage service associated with archives relating to mailboxes in MailboxDatabase1 and MailboxDatabase2 will reside on the first EV server, archived data will have to be transferred over MSMQ to the first EV server.
